| * Bluetooth: Fix sending HCI_Disconnect only when connectedVishal Agarwal2012-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | HCI_Disconnect should only be sent after connection is established. If connection is not yet established and HCI_Disconnect is called then disconnection complete will be received with a handle which does not exist and hence this event will be ignored. But as mgmt.c will not receive this event, its variable for pending command is not cleared.This will result in future Disconnect commands for that BD Address to be blocked with error busy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If remote device sends bogus RFC option with invalid length, undefined options values are used.

| * Bluetooth: Fix deadlock and crash when SMP pairing times outJohan Hedberg2012-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The l2cap_conn_del function tries to cancel_sync the security timer, but when it's called from the timeout function itself a deadlock occurs. Subsequently the "hcon->l2cap_data = NULL" that's supposed to protect multiple calls to l2cap_conn_del never gets cleared and when the connection finally drops we double free's etc which will crash the kernel. This patch fixes the issue by using the HCI_CONN_LE_SMP_PEND for protecting against this. The same flag is also used for the same purpose in other places in the SMP code.

For LE if connection is successful it did not necessarily mean that pairing is also done but if the connection is unsuccessful it should be assumed that pairing procedure is also finished. This patch registers a new function with connect_cfm_cb callback for LE link which sends the pairing complete signal to user space if connection is unsuccessful.

We therefore need to cancel the remain-on-channel and flush the related work structs so they don't run after the interface has been removed or even destroyed. It's also possible in this case that an off-channel SKB was never transmitted, so free it if this is the case. Note that this can also happen if the driver finishes the off-channel period without ever starting it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mesh station that joins an MBSS is reachable using mesh portal with 6 address frame by mesh stations from another MBSS if these two different MBSSes are bridged. However, if the mesh station later moves into the same MBSS of those mesh stations, it is unreachable by mesh stations in the MBSS due to the mpp_paths table is not deleted. A quick fix is to perform mesh_path_lookup, if it is available for the target destination, mpp_path_lookup is not performed. When the mesh station moves back to its original MBSS, the mesh_paths will be deleted once expired. So, it will be reachable using mpp_path_lookup again.

* | Bluetooth: Filter duplicated reports in LE scanAndre Guedes2012-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables filtering duplicated advertising reports during LE scan. Some LE devices advertise using very small intervals generating lots of equal advertising report events to the host. Each event generates a mgmt_device_found event which is copied to userspace. Enabling this feature, duplicated advertising reports are filtered at controller's link layer. This way, the controller doesn't wake up the host to report duplicated advertising reports and, consequently, less data is copied to userspace.

| | | | | | | | | | | | | | | | | | This patch renames L2CAP_LE_DEFAULT_MTU macro to L2CAP_LE_MIN_MTU since it represents the minimum MTU value, not the default MTU value for LE.

* | Bluetooth: Change default MTU for L2CAP ATT channelAndre Guedes2012-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the default MTU value for L2CAP ATT fixed channel to L2CAP_DEFAULT_MTU (672 octets). Differently from others L2CAP channels, in L2CAP ATT fixed channel there is no MTU negotiation. The MTU value for that channel is up to the L2CAP implementation. The only restriction in L2CAP spec is the MTU value must not be less than 23 octets. At ATT protocol level (on top of L2CAP), we have the ATT_MTU which defines the maximum size of any ATT message sent between client and server. GATT profile defines ATT_MTU default value to 23 octets. If a GATT based profile wants to use ATT_MTU greater than 23 octets (e.g. HID over GATT profile), it should negotiate a new value by executing the GATT Exchange MTU sub-procedure. Thus, in order to support any value of ATT_MTU negotiated at ATT protocol level, our L2CAP implementation should have L2CAP ATT fixed channel MTU equal or greater than ATT_MAX_MTU (512 octets).

* | Bluetooth: Fix not removing hci_conn for failed LE connectionAndrzej Kaczmarek2012-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes way LE Connection Complete event with error status are handled. BDADDR returned in such event packet do not need to be valid and should not be used to search for existing hci_conn. Instead, any hci_conn with BT_CONNECT state should be matched since there can be only one pending LE outgoing connection at any time. If not handled properly, appriopriate hci_conn will not be removed and subsequent connection to given peer will try to reuse it without making actual connection attempt. 2012-05-07 11:21:39.133378 < HCI Command: LE Create Connection (0x08|0x000d) plen 25 bdaddr 00:22:D0:10:13:EE type 1 2012-05-07 11:21:39.138774 > HCI Event: Command Status (0x0f) plen 4 LE Create Connection (0x08|0x000d) status 0x00 ncmd 1 2012-05-07 11:21:44.752854 < HCI Command: LE Create Connection Cancel (0x08|0x000e) plen 0 2012-05-07 11:21:44.759475 > HCI Event: Command Complete (0x0e) plen 4 LE Create Connection Cancel (0x08|0x000e) ncmd 1 2012-05-07 11:21:44.764479 > HCI Event: LE Meta Event (0x3e) plen 19 LE Connection Complete status 0x02 handle 0, role master bdaddr 00:00:00:00:00:00 (Public) [14898.739425] [6603] hci_connect: hci0 dst 00:22:D0:10:13:EE [14898.739429] [6603] hci_conn_add: hci0 dst 00:22:D0:10:13:EE [14898.739434] [6603] hci_conn_init_sysfs: conn ffff880079f03000 [14898.739440] [6603] hci_send_cmd: hci0 opcode 0x200d plen 25 [14898.739443] [6603] hci_send_cmd: skb len 28 [14898.739487] [6603] hci_chan_create: hci0 conn ffff880079f03000 ...
